Considerable difficulty is at present experienced with pumps now on the market due to the structuralarrangement of'the same being such that when repairs are necessary, such as the replacement of the plunger leathers, the

entire pump or a considerable part thereof has to be removed from the well.

According to my inventionphowever, and where it is possible for one-todescend into 56 the well, it is not necessary to disturb the leathers and replace the parts.

.5' and being provided above the nipplewith pump as the construction provided-is such 1 that one by descending into the well and due to the construction provided, can obtain easy access to the plunger and insert newplunger The pump cylinderl iis of predetermined length and diameter depending on'thecapac ity and stroke required. -Theuppe'r' end'of the cylinder is received within a collar 2being butted against a gasket 3engaging an internal ledge formed on the collar. The lower end of the cylinder isgreceived within a collar 4, the lower end of the collar being internally screw threaded to receive a nipple an inserted valve seat 6. A weighted valve 7 of well known type is located at thelower end of the cylinder being ammed between the cylinder and the lower collar, such valve being designed to open upwardly on dissection stroke of the plunger later described and to close downwardly against theseat 6.

A closure cap 8 is applied on the upper end of the collar 2; a gasket. 9 being inserted and the cap and the collars are provided with side lugs 'lOwhich are provided with holes; 11 to receive similar tie rods or bolts 12 I which have screw threaded ends. The lower ends of the bolts are provided above and below the lugs of the lower collar with nuts 13 and 14 which nuts when tightened up permanently fasten the tie rods "to said latter collar. The upper ends of the bolts are provided with nuts 15 which when screwed down permanently fasten the cap in place and the several parts together-as will be readily understood. p y

The collar 2 is provided with a side open ing 2 and is flanged and faced as 'shown so that it can be fastened by bolts 16 to the flanged and faced side of avertically :dis-

posed sleeve 16 which has the ends thereof screw threaded; 7 A gasket 17 isplace'd 'between theflanges to insure of a 'water' tight joint. It will be observed that the sleeve is provided with an internal partition 18 above which is an L-shaped passageor duct 19 coin municating with the opening 2.. r q

f A sleeve 20 'is screw threaded to the lower end of the nipple 5and the sleeve is pro 10o vided witha laterally extending upturned elbow 21, the elbow receiving the screw threaded lower end of a supporting pipe 22, the upper end of which is screwed into the lower end of the sleeve 16. A plug 23 is inserted at the lower end of the pipe 22 to prevent water from passing upwardly through such pipe as said pipe is simply used-as a reinforcement for the sleeve 16. A water pipe 24 is screw threaded into the lower end of the sleeve and extends downwardly 'into the well as is usual. A water pipe 25 is screw.

threaded into'the upper end of the sleeve 16 and theupper-end of the water pipe screwthreads into a downturned elbow 26 formed integrally "with'a. top sleeve 26, the latter sleeve being aligned with the central vertical axis of'the cylinder which it overlies.

1 water delivery pipe 27 extends upwardly fromfthe sleeve 26 to the top of the well and-I have herein fshowna bushing 28 as screwthreading intothe sleeve 26 and screw threaded toreceive the-pipe: 27. A comparativelyshort upper cylinder 29 is screw threaded into the lower end of the sleeve 26 and.

this cylinder slidably receives, an upper plunger 30 carried by the upper end of an outlet pipe 31, the lower end of which screw threads centrally into the cap 8., v

- The plunger30 is'shown'as formed from a; leather fastened between two nuts applied on the upper screw threaded-end of the pipe Within thecylinder 1,1 locate slidably the lower or main pump plunger 32,the'details of which will be later described and this plunger is detachably connected to the lower end of the plunger rod 33 which passes freely upwardly through the cap, the pipe 31, the sleeve 26 and the pipe 27 to the top-of the 2 well at which point means not'herein-shown is provided for reciprocating the rod in the usual manner. It will be particularlyfobmediate ring 37 and'38 are placed ion the sleeve and the customary plunger leathers 39 and 40 envelope the rings-and are caught respectively, the upper one between the rings andthe lower one between the intermediate ring and the flange 36. The upper ring is providedwith a three armed bridge 41 within which is located a gravity; valve 42 engageable with the seat formed by the flange 35, the valve being providedwith a centretit 43 as is usual. The plunger parts are fas tened together by three similar bolts 44 passing downwardly through the arms of the bridge, the said bolts having their heads 45 engaging the flange 36 and their upper ends screw threaded to receive nuts 46 engaging the upper edges of the-arms of the bridge as best shown in Figure 7.

. Centrally to the bridge, I secure a short rod 4? which has the upper end screw thread- 5 ed and enteringa coupling sleeve 48, the coupling sleeve being screw threaded on the end of the pump rod 33. V

The above constructionof the. plunger permits the plunger to be taken apart by undoing the nuts and removing the bolts and obviously when this is done, the rings can be lifted to permit of the removal of worn leathers, and the insertion of new leathers.

This being accomplished, the bolts can be the nuts-applied and tightre-inserted and ened up.

In order that the advantages ofmy pump construction may be fully understood,-I will now describe the manner in which one will replace the Worn leathers of the plunger.

nection, it will be noted that theupp'er plung-; 'er' 30' is free to slide upwardly in theupper cylinder which latterinactual practice will probablybe eight inches long and say two inches in diameter. This gives access to the handle orthelike willbe pressed down to bring the plunger 32 to the upper end of its stroke which is in a location below the outlet 2. .Accordingly, when the cap'is raised as above explained, the coupling sleeve 48'appears, such sleeve protruding above the upper levelof the collar 2,-it being here observed that the-cap 8 is arched in vertical cross-section. V V V .1 Q T The operator then uses his wrench to un-j screw the'coupling sleeve from the lower end ofthe pump rod and here itwill be notedthat, asthe pump rod has not been disconnected from the pump handleqor the like at its upper end, the said rod isanchored and as the mam plunger'can rotate in the main cylin-i der, the coupling sleevecan be readily disconnected. Having disconnected the coupling sleeve, one then swings the raised capS laterally and this can be readily done as the upper plunger isfree to swing in-theupper cylinder and ample clearancespace is reserved between the pipe'31 and the cylinder plunger-rodand here I mightexplain that prior .to descending the well, the pump 29. YVhile holding the cap and contained plunger rod in its latter position, one grabs the short rod 47 and lifts the main plunger from the cylinder 1. The nuts 46 can then be undone and the new leathers substituted for the worn ones.

This being accomplished, the repaired plunger 32 is inserted again in the cylinder 1 and shoved down. The cap 8 is swung back to a position above the collar 2 being retained in an elevated position until the short length of rod 47 has been screwed back into the coupling sleeve 48. Finally the cap 8 is dropped down to its initial position and 5 receives the upper ends of the bolts 12 and the nuts 15 are reapplied and tightened up.

It will be particularly noted that the upper plunger in contact with its cylinder prevents any leakage of water when the pump 0 is in use a nd'such arrangement permits of the necessary free up and lateral movement required to position the cap 8 so that the dis.- connected main plun er can be freely raised out of the main cylinder and further it will 5 be seen that the construction provided permits of the easy and quick replacement of worn leathers without having to remove the pump from the well or disconnect any of the pump parts other than the cap 8 and the main 0 plunger so that the complete work can be done by a single operator.

The pump operates in the ordinary manner, water rising in the lower end of the cylinder 1 on the up stroke of the plunger 32,

5 the valve in the lower end of said cylinder opening on such stroke. On the down stroke of said plunger, the plunger valve 42 opens and the water entering above the plunger is discharged upwardly through the pipe 2'? 0 in the subsequent up stroke of the plunger,

such water passing to the pipe 27 through both of the pipes 31 and 25, the. greater portion going throughthe pipe due to its larger cross sectional area.

Vhile I have given a detailed description of the various collars, sleeves and elbows utilized, it will be readily understood that these can be modified without departing from the spirit of the invention.

a If the valve 7 should at any time need'to be replaced, this can be accomplished by undoing the bolts 16 which permits the main cylinder and parts associated therewith to be raised, the lower end of the cylinder lift- .3 ing out of the collar 4 and exposing the valve 7, it being of course understood that the nuts 15 are undone. Y
